Titus Arch: This is the oldest existing arch building in Rome. It was built by Domitian in 8 1 a.d. to commemorate his brother Titus and his father Titus Flavius Caesar Vespasianus Augustus, who suppressed the Jewish rebellion. (that is, the destruction of the temple in the Bible)
Antony Shelter and Faustina: This temple was built by Antony Shelter for his pious wife Faustina in 4 1 A.D., and it is also the best preserved temple. Because it has a baroque top, the temple has an incongruous visual impact.
Senate: This 3rd century Senate still retains its original multi-color mosaic floor, with 300 elders sitting on the business steps and the speaker's podium.
